GREENFIELD — For the second time in two weeks, TD Bank, at 324 Main St., was robbed at gunpoint.

Police are once again seeking a suspect that brandished a semi-automatic handgun.

According to Greenfield Police Detective Lt. Daniel McCarthy, the bank was robbed Sunday at about 2:40 p.m.

“The suspect walked in, waving a gun, and ordered the clerk to give him money. Then he fled the scene on foot,” said McCarthy. “He fled out the back door, and was last seen heading north on School Street, from the back of the building.”

McCarthy said two people were in the bank at the time of the robbery.

The suspect had not been apprehended as of Sunday evening.

The suspect was wearing a gray hooded sweatshirt, with a ski mask over the lower part of his face and dark sunglasses. He is described as a white male between 5 foot, 5 inches to 5 foot, 10 inches. He was also wearing dark pants and gloves, and the gun appeared to be a large, semi-automatic handgun.

The amount of money taken has not been disclosed.

McCarthy said Sunday night the crime is still under investigation.

On Feb. 17, just before noon, the same bank was robbed at gunpoint by a suspect wearing similar apparel and armed with a semi-automatic handgun.

The police have security camera video footage of both incidents.

Robbery with any kind of gun also carries a minimum sentence of five years in state prison, or 15 years in subsequent offenses.
